ABSTRACT
We study a family of type II multiple orthogonal polynomials. We consider orthogonality conditions with respect to a vector measure, in which each component is a q-analogue of the binomial distribution. The lowering and raising operators as well as the Rodrigues formula for these polynomials are obtained. The difference equation of order r + 1 is studied. The connection via limit relation between four types of Kravchuk polynomials is discussed.

摘要
我们研究一族 II 型多重正交多项式。我们考虑关于向量测度的正交条件,其中每个分量都是二项式分布的q类比。得到了这些多项式的降和升算子以及罗德里格斯公式。 研究了r +1阶差分方程。讨论了四种Kravchuk多项式之间通过极限关系的联系。
